The LCP is used to automatically reach the same, and process the size of the package, detect looped-back links and other common configuration errors, and terminating links. Other optional devices provided are: authentication of the same unit identifier in the link, and decisions when link function is normal or when the link fails. In order to use enough convenience in a very wide environment, PPP provides LCP.
There are 3 classes of the LCP package:
Link Configuration Package for establishing and configuring links (Configure-Request, Configure-Ack, Configure-Nak, and Configure-Reject). The link end package is used to end a link (Terminate-Request and Terminate-ACK) link repair package is used to manage and debug a link (Code-Reject, protocol-reply, echo-request, echo-reply) Discard-request).
